Pedophilia or pædophilia (see spelling differences) is the primary or exclusive sexual attraction by adults to prepubescent youths. A person with this attraction is called a pedophile or paedophile. The ICD-10 and DSM IV, which are standard medical diagnosis manuals, currently describe pedophilia as a paraphilia and mental disorder of adults or older youths, if it causes clinically significant distress or impairment in social, occupational, or other important areas of functioning.
